139230-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139230-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,3 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139230-46:
(8*1)+(7*3)+(6*9)+(5*2)+(4*3)+(3*0)+(2*4)+(1*6)=119
119 % 10 = 9
So 139230-46-9 is a valid CAS Registry Number.
